Sub pixel rendering (SPR) is a technique to enhance resolution by havingneighboring pixels to share some common sub-pixels. The two-in-onearrangement is a common SPR approach where sub-pixels of a same colormay share a single metallic mask aperture. The manufacturing isrelatively simple, and has a longer operation life under identicalmanufacturing condition. However, the driving integrated circuit (IC)becomes more complicated compared to a traditional design as driving hasto be conducted from different directions and the driving logic isdifferent.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following descriptions for the respective embodiments are specificembodiments capable of being implemented for illustrations of thepresent invention with referring to appended figures.

FIG. 1 is a structural schematic diagram of a display panel 10 accordingto a first embodiment of the present invention. As shown in FIG. 1, thedisplay panel 10 includes multiple parallel scan lines 100 at intervalsand multiple parallel data lines 200 at intervals. The data lines 200and the scan lines 100 cross each other and are insulated from eachother. A nth scan line 100, a (n+1)th scan line 100, a mth data line200, and a (m+1)th data line 200 jointly define a first pixel area A1.The nth scan line 100, the (n+1)th scan line 100, a (m+2)th data line200, and a (m+3)th data line 200 jointly define a second pixel area A2.The nth scan line 100, the (n+1)th scan line 100, a (m+4)th data line200, and a (m+5)th data line 200 jointly define a third pixel area A3.Each of the first, second, and third pixel areas A1, A2, and A3 includesa number of sub-pixel units 300. Each sub-pixel unit 300 includes afirst sub-pixel 310, a second sub-pixel 320, and a third sub-pixel 330.The sub-pixel units 300 in the first pixel area A1 and the sub-pixelunits 300 of the third pixel area A3 are disposed in a structurallysymmetric manner relative to the second pixel area A2. n is a positiveinteger greater than or equal to 1, m is a positive integer greater thanor equal to 1.

For example, the scan lines 100 are extended along a first direction andarranged at intervals along a second direction. The data lines 200 areextended along the second direction and arranged at intervals along thefirst direction. The data lines 200 and the scan lines 100 are insulatedfrom each other. The first direction may be the X or Y direction. Thesecond direction may also be the X or Y direction. When the firstdirection is X, the second direction is Y. When the first direction isY, the second direction is X. The present embodiment has the firstdirection as the X direction, and the second direction as the Ydirection.

The first, second, and third pixel areas A1, A2, and A3 are lightgeneration areas. Each sub-pixel unit 300 in the first pixel area A1 maybe a red sub-pixel (R), a green sub-pixel (G), or a blue sub-pixel (B).Correspondingly, the first pixel area A1 covers a color resist layer ofa same color as its sub-pixel. For example, if the first pixel area A1has a red sub-pixel, the first pixel area A1 covers the red colorresist. Each sub-pixel unit 300 of the second pixel area A2 may be a redsub-pixel (R), a green sub-pixel (G), or a blue sub-pixel (B).Correspondingly, the second pixel area A2 covers a color resist layer ofa same color as its sub-pixel. For example, if the second pixel area A2has a green sub-pixel, the second pixel area A2 covers the green colorresist.

Each sub-pixel unit 300 includes a first sub-pixel 310, a secondsub-pixel 320, and a third sub-pixel 330. The sub-pixel units 300 in thefirst pixel area A1 and the sub-pixel units 300 of the third pixel areaA3 are structurally disposed in a symmetric manner relative to thesecond pixel area A2. Therefore, the display panel 10 may drivesub-pixel units 300 starting from the first pixel area A1 in a samemanner as the display panel 10 drives the sub-pixel units 300 startingfrom the third pixel area A3. As such, the complexity of the driving ICfor the display panel 10 to the sub-pixel units 300 is reduced, and thedesign of the driving IC then would be less difficult.

In the present embodiment, a second sub-pixel 320 electrically connectto the (m+2)th data line 200 is disposed in the first pixel area A1, andanother second sub-pixel 320 electrically connect to the (m+4)th dataline 200 is disposed in the third pixel area A3.

Specifically, in the present embodiment, when the first, second, andthird sub-pixels 310, 320, and 330 are red, green, and blue sub-pixels,respectively, two second sub-pixels 320 are respectively disposedsymmetrically in the first and third pixel areas A1 and A3 relative tothe second pixel area A2, so as to maintain the symmetry between thesub-pixel units 300 of the first and second pixel areas A1 and A3relative to the second pixel area A2.

As described above, the present invention teaches a display panelincluding multiple parallel scan lines at intervals and multipleparallel data lines at intervals. The data lines and the scan linescross each other and are insulated from each other. A nth scan line, a(n+1)th scan line, a mth data line, and a (m+1)th data line jointlydefine a first pixel area. The nth scan line, the (n+1)th scan line, a(m+2)th data line, and a (m+3)th data line jointly define a second pixelarea. The nth scan line, the (n+1)th scan line, a (m+4)th data line, anda (m+5)th data line jointly define a third pixel area. Each of thefirst, second, and third pixel areas includes a number of sub-pixelunits. The sub-pixel units in the first pixel area and the sub-pixelunits in the third pixel area are disposed in a structurally symmetricmanner relative to the second pixel area. Therefore, the display panelmay drive sub-pixel units starting from the first pixel area accordingto a same driving logic as the display panel drives the sub-pixel unitsstarting from the third pixel area. As such, the sub-pixel units may bedriven by a same driving IC, the complexity of the driving IC to thesub-pixel units is reduced, and the design of the driving IC then wouldbe less difficult.

FIG. 2 is a structural schematic diagram of a display panel 10 accordingto a second embodiment of the present invention. As shown in FIG. 2, thepresent embodiment is generally structured identically to the previousembodiment. The difference lies in that the first pixel area A1 and thesecond pixel area A2 jointly form a first area A12, which has a firstsub-pixel 310, a second sub-pixel 320, and a third sub-pixel 330.Alternatively, the second pixel area A2 and the third pixel area A3jointly form a second area A23, which has a first sub-pixel 310, asecond sub-pixel 320, and a third sub-pixel 330.

Specifically, in the present embodiment, the first and second pixelareas A1 and A2 jointly form a first area A12, and the first area A12has a first sub-pixel 310, a second sub-pixel 320, and a third sub-pixel330.

As the sub-pixel units 300 in the first pixel area A1 and the sub-pixelunits 300 of the third pixel area A3 should be disposed in astructurally symmetric manner relative to the second pixel area A2, thesecond and third pixel areas A2 and A3 jointly form a second area A23,and the second area A23 has a first sub-pixel 310, a second sub-pixel320, and a third sub-pixel 330.

Specifically, the first sub-pixel 310 is a red sub-pixel (R), the secondsub-pixel 320 is a green sub-pixel (G), and the third sub-pixel 330 is ablue sub-pixel (B). A first sub-pixel 310, two second sub-pixels 320,and a third sub-pixel 330 jointly form a pixel group 1000.

Specifically, when the first sub-pixel 310, the second sub-pixel 320,and the third sub-pixel 330 are respectively red, green, and bluesub-pixels, a first sub-pixel 310, two second sub-pixels 320, and athird sub-pixel 330 jointly form a pixel group 1000. In other words, apixel group 1000 includes (¼)R, ( 2/4)G, and (¼)B four sub-pixel units300. This is because human eye is most sensitive to the color green, andtherefore each pixel group 1000 includes two green sub-pixels forenhanced visual effect.

Specifically, in the present embodiment, the (m+1)th data line 200 iselectrically connected to a first sub-pixel 310, the (m+2)th data line200 is electrically connected to a second sub-pixel 320, the (m+3)thdata line 200 is electrically connected to the third sub-pixel 330, the(m+4)th data line 200 is electrically connected to another secondsub-pixel 320. The (m+1)th, (m+2)th, (m+3)th, and (m+4)th data lines 200jointly drives a pixel group 1000.

Furthermore, to drive a pixel group 1000, four separate data lines arerequired. Then, as described above, when the first sub-pixel 310, thesecond sub-pixel 20, and the third sub-pixel 330 are respectively red,green, and blue sub-pixels, a first sub-pixel 310, two second sub-pixels320, and a third sub-pixel 330 jointly form a pixel group 1000. Eachpixel group 1000 therefore includes a red sub-pixel, two greensub-pixels, and a blue sub-pixel. Then, the (m+1)th data line 200 iselectrically connected to a red sub-pixel, the (m+2)th data line 200 iselectrically connected to a green sub-pixel, the (m+3)th data line 200is electrically connected to a blue sub-pixel 330, and the (m+4)th dataline 200 is electrically connected to another green sub-pixel. As such,the (m+1)th, (m+2)th, (m+3)th, and (m+4)th data lines 200 jointly drivesa pixel group 1000.

Furthermore, according to FIG. 2, when driving starts from the firstpixel area A1, the sub-pixel units 300 are driven in the order RGBG/RGBGand, when driving starts from the third pixel area A3, the sub-pixelunits 300 are driving in the same order RGBG/RGBG. In other words, asame driving logic is applied when the display panel 10 drives thesub-pixel units 300 from its upper left corner, or when the displaypanel 10 drives the sub-pixel units 300 from its upper right corner.Therefore, a same driving IC may be used to drive the sub-pixel units300. The driving IC for the sub-pixel units 300 may be simplifiedaccordingly, reducing the difficulty in designing the driving IC.

Selectively, the second sub-pixel 320 electrically connected to the(m+2)th data line 200 is disposed in the first pixel area A1, andanother second sub-pixel 320 electrically connected to the (m+4)th dataline 200 is disposed in the third pixel area A3.

Specifically, in the present embodiment, when the first, second, andthird sub-pixels 310, 320, and 330 are red, green, and blue sub-pixels,respectively, two second sub-pixels 320 are respectively disposedsymmetrically in the first and third pixel areas A1 and A3 relative tothe second pixel area A2, so as to maintain the symmetry between thesub-pixel units 300 of the first and second pixel areas A1 and A3relative to the second pixel area A2.

FIG. 3 is a structural schematic diagram of a display panel 10 accordingto a third embodiment of the present invention. As illustrated, thepresent embodiment is generally structured identically to the firstembodiment. The difference lies in that the second sub-pixels 320electrically connected to the (m+2)th and (m+4)th data lines 200 areboth disposed in the second pixel area A2, as shown in the areadelimited by the (n+1)th and (n+2)th scan lines.

Specifically, in the present embodiment, when the first, second, andthird sub-pixels 310, 320, and 330 are red, green, and blue sub-pixels,respectively, and two second sub-pixels 320 electrically connected tothe (m+2)th and (m+4)th data lines 200, respectively, are both disposedin the second pixel area A2. In this way, the two second sub-pixels 320are adjacent to each other and they may be simultaneously formed in asingle process, thereby reducing manufacturing complexity and productioncost. In addition, as the two second sub-pixels 320 are both disposed inthe second pixel area A2, they may be formed through a single metallicmask aperture for enhanced simplicity.

Selectively, one embodiment has a first sub-pixel 310 and a secondsub-pixel 320 both disposed in the first pixel area A1. Alternatively,another embodiment may have a first sub-pixel 310 and a second sub-pixel320 both disposed in the second pixel area A2.

Specifically, the first, second, and third sub-pixels 310, 320, and 330are red, green, and blue sub-pixels, respectively, there are three pixelareas, namely, the first pixel area A1, the second pixel area A2, andthe third pixel area A3, each of the first, second, and third pixelareas A1, A2, and A3 includes at least a sub-pixel unit 300, the first,second, and third pixel areas A1, A2, and A3 provides at least a pixelgroup 1000, and a pixel group 1000 includes a red sub-pixel, two greensub-pixels, and a blue sub-pixel. Then, according to commoncombinatorics knowledge, one embodiment may have a first sub-pixel 310and a second sub-pixel 320 both in the first pixel area A1.Alternatively, another embodiment may have a first sub-pixel 310 and asecond sub-pixel 320 both in the second pixel area A2. It should beunderstandable that, due to the symmetry between the sub-pixel units 300of the first and second pixel areas A1 and A3 relative to the secondpixel area A2, an embodiment may have a first sub-pixel 310 and a secondsub-pixel 320 both in the third pixel area A3.

Selectively, in one embodiment, each second sub-pixel 320 has an areasmaller than that of each first sub-pixel 310, and also smaller thanthat of each third sub-pixel 330, and each first sub-pixel 310 has anarea smaller than that of each third sub-pixel 330.

Specifically, when the first, second, and third sub-pixels 310, 320, and330 are red, green, and blue sub-pixels, respectively, the greensub-pixel has the smallest area, the blue sub-pixel has the largestarea, and the red sub-pixel has a medium area size, as the greensub-pixel has the highest lighting efficiency, the blue sub-pixel hasthe worst lighting efficiency, and the red sub-pixel has a medium lightefficiency. Through this arrangement of area sizes, the first, second,and third sub-pixels 310, 320, and 330 may provide an optimized visualeffect, thereby enhancing the display quality of the display panel 10.

FIG. 4 is a structural schematic diagram of a display panel 10 accordingto a fourth embodiment of the present invention. As illustrated, thepresent embodiment is generally structured identically to the firstembodiment. The difference lies in that a nth scan line 100, a (n+2)thscan line 100, a mth data line 200, and a (m+1)th data line 200 jointlydefine a fourth pixel area A4, which includes a first sub-pixel 310, asecond sub-pixel 320, and a third sub-pixel 330.

FIG. 5 is a structural schematic diagram of a display panel 10 accordingto a fifth embodiment of the present invention. As illustrated, thepresent embodiment is generally structured identically to the fourthembodiment. The difference lies in that, in the present embodiment, thesub-pixel units 300 are arranged in a repetitive manner duplicating apattern between a nth scan line 100, a (n+1)th scan line 100, and a(n+2)th scan line 100. Specifically, the nth scan line 100, the (n+1)thscan line 100, the (n+2)th scan line 100, a (n+3)th scan line 100, and a(n+4)th scan line 100, and a mth data line 200, a (m+1)th data line 200,a (m+2)th data line 200, a (m+3)th data line 200, a (m+4)th data line200, and a (m+5)th data line jointly define the display panel 10. Thedisplay panel 10 drives the sub-pixel unit 300 from the upper leftcorner in the order RGBG/RGBG. The display panel 10 drives the sub-pixelunit 300 from the upper right corner also in the order RGBG/RGBG, Thedisplay panel 10 drives the sub-pixel unit 300 from the lower leftcorner in the order BGRG/BGRG. The display panel 10 drives the sub-pixelunit 300 from the lower right corner also in the order BGRG/BGRG. Inother words, the display panel 10 drives the sub-pixel units 300 fromits upper left corner in a same manner as when the display panel 10drives the sub-pixel units 300 from its upper right corner, both in theorder RGBG/RGBG. Similarly, the display panel 10 drives the sub-pixelunits 300 from its lower left corner in a same manner as when thedisplay panel 10 drives the sub-pixel units 300 from its lower rightcorner, both in the order BGRG/BGRG. Therefore, the driving IC for thesub-pixel units 300 may be simplified accordingly, reducing thedifficulty in designing the driving IC. Furthermore, the sub-pixel units300 in an area defined by the mth and (m+1)th data lines 200 and thesub-pixel units 300 in an area defined by the (m+4)th and (m+5)th datalines 200 are disposed in a structurally symmetric manner relative to anarea defined by the (m+2)th and (m+3)th data lines 200. Therefore, thepresent invention may improve the phenomenon of colored edges fromsub-pixel units 300 to the display panel 10's left and right sides,thereby enhancing the display quality of the display panel 10.

The display panel taught by the present invention, as the sub-pixelunits in the first pixel area and the sub-pixel units in the third pixelarea are structurally disposed in a symmetric manner relative to thesecond pixel area, may drive sub-pixel units starting from the firstpixel area in a same manner as the display panel drives the sub-pixelunits starting from the third pixel area. Therefore, a same driving ICmay be used to drive the sub-pixel units. The driving IC for thesub-pixel units may be simplified accordingly, reducing the difficultyin designing the driving IC.

FIG. 6 is a structural schematic diagram of a display panel 10 accordingto a sixth embodiment of the present invention. As illustrated, thepresent embodiment is generally structured identically to the fifthembodiment. The difference lies in that, in the present embodiment, thesub-pixel units 300 are arranged in a repetitive manner duplicating apattern between a (m+2)th data line 200, a (m+3)th data line 200, a(m+4)th data line 200, and a (m+5)th data line 200. Specifically, thenth scan line 100, the (n+1)th scan line 100, the (n+2)th scan line 100,a (n+3)th scan line 100, and a (n+4)th scan line 100, and a mth dataline 200, a (m+1)th data line 200, the (m+2)th data line 200, the(m+3)th data line 200, the (m+4)th data line 200, the (m+5)th data line,a (m+6)th data line 200, a (m+7)th data line 200, a (m+8)th data line200, and a (m+9)th data line 200 jointly define the display panel 10.The display panel 10 drives the sub-pixel unit 300 from the upper leftcorner in the order RGBG/RGBG. The display panel 10 drives the sub-pixelunit 300 from the upper right corner also in the order RGBG/RGBG. Thedisplay panel 10 drives the sub-pixel unit 300 from the lower leftcorner in the order BGRG/BGRG. The display panel 10 drives the sub-pixelunit 300 from the lower right corner also in the order BGRG/BGRG. Inother words, the display panel 10 drives the sub-pixel units 300 fromits upper left corner in a same manner as when the display panel 10drives the sub-pixel units 300 from its upper right corner, both in theorder RGBG/RGBG. Similarly, the display panel 10 drives the sub-pixelunits 300 from its lower left corner in a same manner as when thedisplay panel 10 drives the sub-pixel units 300 from its lower rightcorner, both in the order BGRG/BGRG. Therefore, the driving IC for thesub-pixel units 300 may be simplified accordingly, reducing thedifficulty in designing the driving IC. Furthermore, the sub-pixel units300 in an area defined by the mth and (m+1)th data lines 200 and thesub-pixel units 300 in an area defined by the (m+4)th and (m+5)th datalines 200 are disposed in a structurally symmetric manner relative to anarea defined by the (m+2)th and (m+3)th data lines 200. Therefore, thepresent invention may improve the phenomenon of colored edges fromsub-pixel units 300 to the display panel 10's left and right sides,thereby enhancing the display quality of the display panel 10.

The display panel taught by the present invention, as the sub-pixelunits in the first pixel area and the sub-pixel units in the third pixelarea are structurally disposed in a symmetric manner relative to thesecond pixel area, may drive sub-pixel units starting from the firstpixel area in a same manner as the display panel drives the sub-pixelunits starting from the third pixel area. Therefore, a same driving ICmay be used to drive the sub-pixel units. The driving IC for thesub-pixel units may be simplified accordingly, reducing the difficultyin designing the driving IC.

FIG. 7 is a structural schematic diagram of a display panel 10 accordingto a seventh embodiment of the present invention. As illustrated, thepresent embodiment is generally structured identically to the sixthembodiment. The difference lies in that, in the present embodiment, twoadditional rows of sub-pixel units 300 are disposed as the bottommostrows to the display panel 10. The two rows of the sub-pixel units 300are identical to the top two rows of the three rows of sub-pixel units300 between the nth and (n+1)th scan lines 100. The display panel 10then drives the sub-pixel unit 300 from the upper left corner in theorder RGBG/RGBG. The display panel 10 drives the sub-pixel unit 300 fromthe upper right corner also in the order RGBG/RGBG. The display panel 10drives the sub-pixel unit 300 from the lower left corner also in theorder RGBG/RGBG. The display panel 10 drives the sub-pixel unit 300 fromthe lower right corner also in the order RGBG/RGBG. In other words, thedisplay panel 10 drives the sub-pixel units 300 from its upper leftcorner in a same manner as when the display panel 10 drives thesub-pixel units 300 from its upper right, lower left, or left rightcorner, all in the order RGBG/RGBG. Therefore, the driving IC for thesub-pixel units 300 may be simplified accordingly, reducing thedifficulty in designing the driving IC.
